maintenance questions

Well I'm picking up a 1997 Paseo with 74K miles this weekend. It will be my commuter car. Anyways I wanted to order some maintenance stuff so I'm ready for it's arrival. What kind of air filters are you guys using? I can't seem to find a source for Toyota air filters online. I found oil filters, just not air. Also, how much oil does the Paseo hold?

Thanks a bunch
